new life spectrum...come in different sizes...
Some folks were saying NLS pellet does not sink is that true ?
My only complaint with NLS is their consistency. I've had lots that turn to dust in water in mere minutes, while others will stay as pellets days later. Since, IME, texture and hardness of a pellet are factors that affect how well fish eat them, or get used to eating them, this is a pain in the butt for me.
ON pellets are noticeably preferred by my butterflies, and are always consistent.
